Hair clip

ABSTRACT

A hair clip, comprising: a lower clip body and an upper clip body pivotally connected together at one end of each; corresponding locking and fixing devices formed at the other ends of said lower clip body and upper clip body; wherein a plastic slice is formed at an end of an elastic locking clip adjacent to a wall of the locking and fixing device formed at said upper clip body and is pressed against said wall in a tilted relation. The hair clip according to the invention implements an improved locking and fixing method and produces the same locking and fixing effect as the locking and fixing method commonly used for prior art hair clips does. Moreover, since the locking and fixing devices and the plastic slice controlling their switch can be formed one-piece, manufacture of the hair clip is simplified.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The subject invention relates to the field of ornaments, in particular,to a hair clip.

2. Prior Art

Hair clips usually seen in the market generally comprise a lower clipbody and an upper clip body pivotally connected together at one end ofeach. Each of the lower clip body and upper clip body has acorresponding locking and fixing device at the other end to secure thehair between the lower clip body and the upper clip body. When using thehair clip, unlock the fixing device which locks the lower clip body andthe upper clip body, turn the lower clip body, locate the hair to beclamped in the space between the lower clip body and the upper clipbody, and then lock the device to complete the positioning

Unfortunately, the locking and fixing devices of this type of hair clipsare complicated in manufacture. In addition, they are bulky, anddifficult to be assembled. The Chinese patent application withpublication number of CN1131525A makes some improvements to overcome theabove defects. However, the provided hair clip still takes advantage ofthe elastic force of a spring to control the switch of a sliding pin.Since the spring cannot be formed simultaneously with the hair clip,instead, an additional procedure is needed to insert a projecting needleinto the spring, and then further mount them onto the locking and fixingdevice, a lot of manufacture procedures are added. Therefore, there is aneed for further improvement.

On the other hand, the surfaces of the lower clip body and the upperclip body of a usual hair clip are smooth surfaces. Therefore, the cliptends to slip with respect to the hair after the clip is locked andfixed, and then the hair will slide out as a result. To avoid such acase, the above application makes further improvement to the hair clip,i.e., a saw-shaped stripe is formed on the lower surface of the upperclip body (i.e., the surface used for clamping the hair). However,during practical use, the design of such a saw-shaped stripe showsrather limited function of slip resistance. Therefore, there is also aneed for further improvement against it.

SUMMARY OF THE INVENTION

The object of the subject invention is to make improvements against theabove defects of the above application, and thereby provide a novel hairclip to facilitate its manufacture.

To achieve such an object, a hair clip according to the inventioncomprises a lower clip body and an upper clip body pivotally connectedtogether at one end of each. Corresponding locking and fixing devicesare formed at the other ends of the lower clip body and the upper clipbody, one of the corresponding locking and fixing devices including alocking column formed at the other end of the lower clip body, and theother including an elastic locking clip formed at the other end of theupper clip body. A plastic slice is formed at the end of the elasticlocking clip adjacent to a wall of the locking and fixing device formedat the upper clip body. The plastic slice is pressed against the wall ina tilted relation.

According to the invention, the plastic slice is formed at a shoulder ofthe elastic locking clip.

According to the invention, the plastic slice is pressed the wall in adownward tilted relation.

According to the invention, a non-slip layer is fastened onto an uppersurface of the lower clip body.

According to the invention, a saw-shaped stripe is formed on a lowersurface of the upper clip body to further enhance the function of slipresistance.

According to the invention, the nonskid layer is a layer of artificialrubber, natural rubber, silicon gel, emulsoid, PVC, thermoplasticelastomer, or thermoplastic rubber.

According to the invention, the hair clip is completely made of plasticmaterials.

The hair clip according to the invention implements an improved lockingand fixing method and produces the same locking and fixing effect as thelocking and fixing method used for prior art hair clips does. Moreover,since the locking and fixing devices and the plastic slice controllingtheir switch can be formed one-piece, manufacture of the hair clip issimplified. In addition, since there is a non-slip layer formed on theupper surface of the lower clip body, a good function of slip resistanceis achieved. On this basis, the lower surface of the upper clip body isconfigured as saw-shaped, and thus a better function of slip resistanceis realized to clamp a variety of hair style more stably.

DETAILED DESCRIPTION OF THE INVENTION

The hair clip of the invention will be further described with specificembodiments in connection with the appended drawings. It is understoodthat the embodiments are used for explaining, instead of limiting, thescope of the invention.

As is shown in FIGS. 1-3, the hair clip of the invention comprises alower clip body 1, and an upper clip body 2 having one end 20 pivotallyconnected to one end 10 of the lower clip body 1. Each of the lower clipbody 1 and upper clip body 2 has a corresponding locking and fixingdevice at the other ends 10′ and 20′, respectively. One of thecorresponding locking and fixing devices includes a locking column 13formed at the other end 10′ of the lower clip body 1 and the otherincludes an elastic locking clip 23 formed at the other end 20′ of theupper clip body 2. A plastic slice 231 is formed at the end of theelastic locking clip 23 adjacent to a wall 23 a of the locking andfixing device formed at the upper clip body 2, and preferably at theshoulder of the elastic locking clip 23. The plastic slice 231 ispressed against the wall 23 a in a tilted relation, preferably in adownward tilted relation, to keep the elastic locking clip 23 in alocked state. When the locking column 13 is in a locked and fixed stateby flanges 26 and 33, a pressure is generated between an edge 25 of theupper clip body 2 and the lower clip body 1. As a result, when it isrequired to relieve the locked and fixed state, merely press the elasticlocking clip 23, then the plastic slice 231 will be pressed, and theflange 33 will be moved away from the flange 26, forming an open state.The pressure experienced by the edge 25 will push out the lower clipbody 1 quickly. This design can facilitate unlocking the lower clip body1 with one hand for the users. After the finger pressing the elasticlocking clip 23 leaves, the plastic slice 231 will restore so that theelastic locking clip 23 will be locked again.

To achieve the object of effective non-slip, the hair clip of theinvention has a non-slip layer fastened onto an upper surface 12 of thelower clip body 1 (not shown). Such a non-slip layer may be made ofartificial rubber, natural rubber, silicon gel, emulsoid, PVC,thermoplastic elastomer, or thermoplastic rubber, etc. The hair clip ofthe invention may also have a saw-shaped stripe 4 formed on a lowersurface of the upper clip body 2 to further enhance the function of slipresistance.

The stripe 4 may be made of the same material with the upper clip body2, or with the non-slip layer. Preferably, the stripe 4 and the non-sliplayer are made of the same material to apply a more tender pressure ontothe hair while providing a good function of slip resistance.

The plastic slice 231 eliminates the use of a metallic string in hairclips which are common in the market, and thus ensures that the hairclip of the invention is completely made of plastic materials.

The hair clip according to the invention implements an improved lockingand fixing method and produces the same locking and fixing effect as thelocking and fixing method commonly used for prior art hair clips does.Moreover, since the locking and fixing devices and the plastic slicecontrolling their switch can be formed one-piece, manufacture of thehair clip is simplified. In addition, since there is a non-slip layerformed on the upper surface of the lower clip body, a good function ofslip resistance is achieved. On this basis, the lower surface of theupper clip body is configured as saw-shaped, and thus a better functionof slip resistance is realized to clamp a variety of hair style morestably.
